Non sequitur. You are going back a few centuries. If you are saying there is not enough gold, that is foolish. There is plenty of gold. Were the dollar to be pegged to gold at any rate the economy would become much more stable after a probably short but severe depression as the debt is retired or at least reduced to a small proportion of GDP.
If gold was plentiful it wouldnt be a precious metal, neither would it have as much value as it does. There is a finite supply that exists and can potentially be mined. The size of economies does not have a limit.
